I can't boot into custom recovery (TWRP)

I'm having a problem flashing a custom recovery on my Nexus 7. I'm trying to install the TWRP recovery for the "flo" version and it doesn't seem to install. I mean, it says it does in fastboot mode but when I reboot to recovery it goes to the stock recovery instead (the green android with the red triangle) and just stays on that screen for minutes. What gives?

Yep. Solved it though. Apparently in 4.4 they've made it so that the device will replace TWRP with the stock recovery immediately after rebooting if you don't boot into TWRP immediately after installing it using:
fastboot boot name-of-recovery.img
Then you have to change the name of a file while in TWRP. In TWRP go to Mount and select System. Then go back to the main screen and press Advanced > File Manager. Browse to /system and select a file named recovery-from-boot.p and rename it to recovery-from-boot.bak. And you should be able to go into TWRP like normal.

Could you please describe this procedure detailed?
Where can I find the "Mount" option?
Must my device being rooted?

Some tricks for you guys if you are stuck like I was :
-if you can't boot to custom recovery, try naming your custom recovery img "recovery.img" instead of "twrp.img" when you flash it.
so --> "fastboot flash recovery recovery.img" will be the command you execute.
-if you can't flash recovery at all, try executing the command without the phone plugged, then plug the device when you see the prompt "<waiting for any device>"
Hope this helps !

Stuck on TWRP logo

Hello, my problem here is whenever I wanted to boot to recovery, it got stuck at the TWRP logo and cannot enter the recovery. Can anybody help? I already tried to flash it manually with the latest image and it still brings the same problem.

Did you follow the instructions to flash TWRP step-by-step?
*(Before starting, rename your TWRP image to twrp-recovery.img for convenience)
*This step is optional
Put your device into fastboot
Connect it to your PC
Open an adb command window
fastboot devices
fastboot oem unlock
fastboot flash recovery twrp-recovery.img
Then once it's done, you can disconnect your device and turn it off.
Once it's off, you can boot into recovery mode, and you should be able to access the recovery menu.
Cheers!

LG G4 H815 frozen on LG logo after attempting root/TWRP

Attempted to root phone use ADB and fastboot.
during process noticed difficulty in getting recovery mode open manually and had to use adb reboot recovery, whereupon android recovery picture was there but no menu options.
Could not install TWRP conventionally thus attempted the method shown here.
"NSTALL TWRP
Make sure you have ADB and Fastboot installed.
I always put TWRP.img in the ADB folder - so if I want to boot into TWRP with out installing it this is what I do:
make sure you open a command prompt in the ADB folder "VERY IMPORTANT" and type:
adb reboot bootloader <enter>
fastboot boot TWRP.img <whatever your TWRP image is called in your ADB folder><enter> dont forget the .img at the end
That will re-start your phone straight into TWRP - You can transfer files to and from your computer while in recovery.
If you want to install TWRP permanently, copy your TWRP image to your mobile "while you are in TWRP RECOVERY mode" then press install, then select images, then select recovery NOT BOOT, then swipe to flash. This method does not install TWRP app on your phone, all you need is a reboot app from the play store that will re-boot you into recovery. "
Flashed both twrp image and super-su within the TWRP booted from pc through adb (as shown in the previously mentioned method).
Upon reboot phone has hung at LG symbol. LED is flashing. ADB recognises device as connected however won't respond to reboot requests.
How do i fix this?

Custom recovery TWRP for Infocus bingo 21 m430

Working TWRP custom recovery for infocus m430 bingo 21.
To do this, you would require:
data cable if not rooted phone
stock marshmallow running infocus m430 bingo 21
if not rooted, you need adb and fastboot installed on your computer-> google this if never heard of.
download attachments of this post(twrp_recoveryimg)
Problems:
Before you do this, you need to know the temporary problems you would encounter and their solutions
TWRP is in other language but you can use this link to bring it back to english, 1 time thing
http://www.teamandroid.com/2017/04/30/change-twrp-recovery-language-english/
if the above link does not work out, there are lot of youtube videos to enable english in twrp. google out.
once mobile boots into recovery, it will not come back to normal. There is a bit being set by infocus on some partition to reboot to recovery always. Until i find it, you would have to use following the process below to come back to normal boot.
Steps to come back to normal boot
1. in recovery, select option advanced
2. select adb sideload option
3. swipe to start sideload(this will start adb in recovery mode)
4. cancel
5. in your computer type
Code:
adb reboot bootloader
6. After mobile shows fastboot mode: in top of the screen with infocus logo type the below command
Code:
fastboot continue
7. This should boot your device back to normal android boot.
8. You have to do this every time you boot to recovery.
Now follow the below procedures to get a custom recovery on your mobile.
Procedure 1 : (does not require root)
unlock developer options -> google this if you never knew this until now.
unlock oem. Do this by going to developer options -> oem unlocking(enable).
unzip the recovery image attachment
enter fastboot by typing following command.
Code:
adb reboot bootloader.
flash twrp_recovery.img in the attachement. Do this by using following commands.(place your twrp_recovery.img in the current directory of terminal / cmd)
Code:
fastboot erase recovery
fastboot flash recovery twrp_recovery.img
Procedure 2 : (requires root) I have not tried this but it would work. Try it on your own risk.
Download the attachments
send them to your mobile sdcard
install mobile uncle tools or similar app from play store which would flash recovery images
select install recovery and point to the twrp_recovery.img in your sdcard.
Message me in case of questions or reply this thread.

Sir,where to type the code 'adb reboot bootloader' and other codes?

Want your contact number, for the purpose of custom recovery.
I tried that steps many times on my phone via pc. So help me for the custom recovery. I want your contact number to do this process correctly without worrying any problem occurs on my phone.

You should be able to find youtube video on how to install adb and fastboot online. After that, you should type those commands in command prompt in windows computer if you have or in terminal if you have linux or mac.

Problem while using adb fastboot method in In focus M425
What about infocus M425 phone ????

TWRP help needed

I unlocked my Nexus 7, though after a TWRP install when selecting recovery mode it stays stuck on the Google logo as if there’s no TWRP; though the command prompt said install was successful.
Any help?

It may be incorrect sequence of steps, note:
"many devices will replace your custom recovery automatically during first boot. To prevent this, use Google to find the proper key combo to enter recovery. After typing fastboot reboot, hold the key combo and boot to TWRP. Once TWRP is booted, TWRP will patch the stock ROM to prevent the stock ROM from replacing TWRP. If you don't follow this step, you will have to repeat the install."
Try this:
Restock
run Android once
flash TWRP
immediately and directly boot TWRP

Will try that!
